    The invention relates to mechanical engineering and can be used in machine tools. A ball screw is known that contains a screw, on the surface of which a return channel is made with lateral guide elements, a nut and balls interacting with it, located in the grooves of the screw and nuts. The bottom of the return channel is curved, and the lateral guiding elements are located at an angle to the latter. An disadvantage of the known device is low manufacturing technology. The purpose of the invention is to improve the technology of manufacturing transmission. This goal is achieved by the fact that in a ball screw drive that contains a screw, on the surface of which a return channel is made with lateral directions, interacting (with it the nut and balls located in the grooves of the screw and nuts, the bottom of the channel is flat, and the sides of the lateral the guide elements forming the channel are beveled at the entrance and exit of the balls and are arranged perpendicular to the bottom. In Fig. 1, a ball screw gear is shown, longitudinal section; Fig. 2 is a top view guiding element; Fig. 3 And in FIG .2; FIG. 4 — section B — B in FIG. 1. FIG. 5 — ball screw mechanism, longitudinal section. The ball screw mechanism comprises a CASE 1. a screw 2 with threads 3 and 4 threads of the thread 4 located in it. A nut 5 from a turn of a mine of 6 threads and sides 7 of a thread profile and balls 8 placed in the grooves of the nut and screw threads. Between the two external sides 4 of the screw thread profile 2, a surface (bottom) 9 was made, for example, by milling. The width of the surface 9, measured in the axial direction of the screw 2 5, is determined by the main distance between the two outer sides 4 of the thread profile. The length, measured almost transversely to the axial direction of the screw 2, is due to the fact that the balls 8 of turns 3 of the thread must fall on the surface 9 and at the same time no longer touch the sides 7 about the fillet of the thread on the side of the nut. This determines the distance d (Fig. 4), which can be somewhat reduced due to the fact that the bottom 9 around the perimeter of the screw is slightly slightly convex. The angle between (between the side guide and the thread profile side 4) of the retraction of the balls 8 is structurally defined in FIG. 1 and 3, if bevels 10 are provided that allow the balls 8 to freely leave their reference line, at the sides of the thread profile. The two guiding elements of Fig. 1, the dotted lines are located almost parallel to one another on the center line, i.e. essentially flat guide surfaces or flat walls 11, which, together with the surface of connector 12 (surface 9, when viewed in axial longitudinal section through screw 2), restrict the V-shaped channel, return the balls 8. Returnable channel (FIG. 1) has a slightly curved shape or a beveled surface 13 to the axis of the channel surface of the connector. Figures 2 and 3 show the shape of the lateral guiding elements 14 thus determined, which are screwed with countersunk screws in the holes 15 and screwed to the surface (bottom) 9, on which there are holes 16 with thread for this. In the process of returning the balls 8 (Fig. 4), instead of circulating one ball around the perimeter of the screw 2, many balls can be placed. The screw is hollow, and both ends of the hollow shaft of the screw are held in the heads of the nut 3, for example, in the self-lubricating meta-ceramic bearings 17 and sealed against the corresponding spacers 18. grease output, as well as water pollution and access. The holes 19 allow the lubricant to be evenly distributed during the reciprocating movement of the aiki 5. The tetrahedron 20 and the connecting steel 21 ensure the activation of the device and its disconnection. The material used to make the side guides should be the same as the material used to make the screw and nut.
